Some of you who are better informed than others when it comes to laser eye surgery. Of course there are many variations, such as LASIK, LASEK, PRK, Wavefront custom LASIK, LASEK and epi-much more, but in reality you can only choose one. Some potential candidates who want an alternative to LASIK surgery because of the horror stories they have heard what you want some information about LASEK eye surgery instead. This article will help clarify the differences between LASIK vs. LASEK.
LASIK (laser assisted in situ keratomileusis) is a laser eye surgery, in a section of the outer eye is cut with a blade called microkeratome. In some surgeries you have seen or heard, may seem like a can opener, but this is simply a circular blade. In some other cases, a laser can be used for greater accuracy, but would result in a slightly more expensive procedure. In any case, this component is cut so that the laser can burn the inner layers of the eye. This new form in the eye so that light rays can focus on a point on the retina, resulting in a clear and undistorted.
In a true LASIK procedure, a type of restraint as a tool is placed over the operated eye to keep the eyelids open. Then the surgeon clamps, drops to numb the eye before surgery, to prevent dry eyes and also to act as an antibiotic. The surgeon then proceeds to operate in the eye with the blade or laser, then pull the flap away to use the laser to the inner layers of the eye. You can see the flashing lights that should last about 1 minute. Thereafter, the surgeon to replace the rear flap in the eye. Throughout the entire procedure, the surgeon is constantly rewet eye drops and smooth the outer surface of the eye. As anesthetic drops were instilled in the eye, you should not feel pain during the procedure. The most intense feeling ever feel a pressure in the eye when the surgeon is cutting the flap.
Furthermore, LASEK (laser epithelial keratomileusis) is a laser eye surgery very similar to LASIK. It is actually a variation of PRK surgery, but instead of direct laser energy, a flap of the outermost layer of the eye known as the epithelium, cut. Before that, the surgeon usually add a few numbing eye drops, followed by the setting in the retainer to keep your eyelids open. The surgeon then proceed to cut the corneal epithelium and add a solution of alcohol in his eyes, to loosen the edges. Once it is loose enough, the surgeon can pull on the flap, after which the laser is shot in the eye, as in LASIK. Once done, the surgeon adds some rewetting eye drops, then the eyes, softening eyes and then reposition the epithelial flap in the eye again.
To conclude the discussion of LASIK vs. LASEK all comes down to whether or not you qualify for LASIK in the first place. This is because LASEK surgery is a fairly long recovery time, even more than PRK, and often suggested as a second option if the patient is not eligible for LASIK.
